Abstract: A method is provided for thermo-chemical dewaxing of a large dimension line or conduit using a Nitrogen Generation System/Emulsion. The method involves introducing an emulsion into the conduit to be dewaxed. The emulsion comprises an internal aqueous phase and an external organic phase. The aqueous phase comprises an oxidizing nitrogen salt, a reducing nitrogen salt and water. The organic phase comprises a non-polar organic liquid, such as kerosene, and a delayed action activator for inducing the reaction of said oxidizing nitrogen salt and said reducing nitrogen salt. The delayed action activator may be a linear, aliphatic polyanhydride, such as poly(adipic anhydride). The emulsion is maintained in the conduit until the delayed action activator induces the reaction of the nitrogen salts to generate nitrogen and heat, thereby fluidizing wax in the conduit. The fluidized wax is then removed from the conduit. The emulsion may be prepared on a production platform or on nearby equipment. Well production may be resumed after the dewaxing treatment.

Inventor: KIM NUNG-SOO P
IPC: H02K53/00
Filed: 1997-01-30
Abstract: This device has a three-pole forced permanent magnet rotary wheel which can be actuated with a small electrical input to produce a powerful high torque. A plurality of permanent magnets referred to as wheel magnets, are mounted in a circular ring manner on the surface of a rotary wheel and they are located equidistant from one another and radially from the center of the rotary wheel. The total number of wheel magnets may be any even number equal to or greater than four depending on the space allowed on the rotary wheel. The polarities of the wheel magnets are alternately positioned juxtaposed to station magnets located adjacent to the rotary wheel. Each station magnet is mounted on a shaft which is, in turn, mounted on a main frame, and the shaft is rotatable by a DC twister. The total number of station magnets is an odd number, which is less than the total even number of the wheel magnets. The station magnets are equidistant from each other and are perpendicular to the respective neighboring wheel magnets. The polarities of the station magnets face towards the right and left sides, in front of the single pole of the neighboring wheel magnets. Each time a DC twister is activated to rotate its associated station magnet through 180 degrees or close to 180 degrees, the repelling and attracting magnetic forces between this station magnet and its neighboring wheel magnet causes the rotary wheel to rotate. A plurality of electrical conducting switches for activating all the twisters are located at specific points on the rotary wheel so that the station magnets are rotated sequentially for producing a continuous rotation of the rotary wheel.

Title: Method of transforming periodic signal using smoothed spectrogram, method of transforming sound using phasing component and method of analyzing signal using optimum interpolation function
Inventor: MASUDA IKUYO
IPC: G10L25/27
Filed: 1997-07-17
Abstract: At a smoothing spectrogram calculation portion, a triangular interpolation function having a frequency width twice that of the fundamental frequency of a signal is obtained based on information on the fundamental frequency of the signal.  The interpolation function and a spectrum obtained at an adaptive frequency analysis portion are convoluted in the direction of frequency.  Then, using a triangular interpolation function having a time length twice that of a fundamental period, the spectrum interpolated in the frequency direction described above is further interpolated in the temporal direction, in order to produce a smoothed spectrogram having the space between grid points on the time-frequency plane filled with the surface of a bilinear function.  Using the smoothed spectrogram, a speech sound is transformed.  Therefore, the influence of periodicity in the frequency direction and the temporal direction can be reduced.
